to check if it is indeed a thermal problem I would run it full speed with the case opened, then do some stress tests. If theres no problem, it is heat related. I once build a HackIntosh from my QS with an Gigabyte M-ATX board, 450W power supply and a GeForce 7600GT in it. Did cut some extra...

thats the thing I was thinking,too.. and yes, my 1400/2400/3400 work with CF cards and adapter,too..but I sometimes prefer to use a new(ly) good IDE drive instead. so install back the IDE drive and after boot pop in a CF card in the PCMCIA slot and see if it is being recognized/formatable

right..other than a real hardware mod..

I‘m looking for tool similar to Phipli‘s Soft-475 but for PPC..there's also ZDNet Clock, MacPro Overclock Tool for Intel Macs but I couldnt find anything for 603e PPC ( as in powerbook 5300)

Oh, the 540c, I misread, sorry, I thought you meant the 5300. On the 540c I did a repaint job, it‘s a 540c black coffee edition now😏

try to identify the original quarz, I'm not sure what the specs are, 3V or 5V.. it seems to be a vintage Epson part? but the small label on it is also on Seiko crystals ( of course the package size and footprint are different) original quarz Epson Seiko

I think the later revisions of the 5300 had darker colored plastics than the earlier ones?

it looks ok, could use a recap of course but it still is bright and clear

I'll try to to speed up the PPC chip up to 117 Mhz via 38 Mhz crystal or resistor re-arranging. from here ( https://alksoft.com/5300_overclock.html) the way via the resistors is free( no parts ordering) but..they are TINY..I mean really tiny. and finding a matching 38 Mhz four pin quarz is...

after some more scratching and cleaning reassemble time and first test boot.. has 8.1 on it and MS Office but wait..maxed out 64 MB RAM, a surprise.. at least something to speed up the cacheless 1995 wonder a bit. I put in a 64GB SD card, copied 8.6 on the first partition and after that...

board out, looks good, no electrolyte spill on it powerboard has a little corrosion but cleaned up ok..also the old battery wonderful turquoise colored gunk, looks like artwork. lol.

Yesterday I got another 5300c, this machine already was on ebay one time, as I could recall it's photos. was well packaged, sold as defect..came in a nice laptop bag full of goodies like an Apple HDI-30 cable, an PCMCIA Ethernet card with dongle, a modem card, all their complete discs and...

agreed, I also had this with a 540c and a 1400/3400 also about the cooling..the 3400's heat sink got a lot warmer after I clocked it to 200 Mhz, I also did add an arctic cooling thermal pad and tiny copper heatsink ( and it has a fan inside)

well, this page refers to two methods of overclocking the 5300, 100 and 117 models by a) changing the bus-to-cpu ratio for the resistors at positions R43, R46, R47, R48, R50, R127, R128, and R129 on the motherboard. https://www.alksoft.com/5300_FAQ/FAQ_A.1.1.php the best photo I could find...

tried this?

try to cross-test the hub on a similar era pc first, maybe its a driver thing, maybe the procols/drivers work better on a pc.

wow, really interesting numbers..this reminds me of my times at a graphic design shop as an an intern, back in 1992 or so. They had a 950 Quadra with a huge 17" CRT..I was working on a Performa. Ram and other hardware was so expensive..but it worked! A lot of hand lettering, copying, scanning...

the Broadcom chip is down left but the pll location seems different? there are two different 1,33Ghz ibook G4, 12" and 14", maybe theres a softmod overclock possibility?

oh, mine didnt look bad either..maybe you can see some green corrosion that wicked through the cable/ connector..

old story, exactly over this whole area ( under the speaker panel) sits the green Varta PRAM battery of death, when it once leaked and electrolyte dripped onto the components beneath it, it is likely damaged/dead ( 47uF cap area)..I had two machines with little corrosion there, also did pay for...
